@conference{10902/2427, year = {2011}, month = {5}, url = {http://hdl.handle.net/10902/2427}, abstract = {In this work, a novel single-longitudinal-mode (SLM) four-wavelength laser configuration for sensing applications in L-band is proposed and experimentally demonstrated. This spectral region presents some advantages for the detection of dangerous gases. The sensor system presented here is based on ring resonators, and employs fiber Bragg gratings to select the operation wavelengths. The stable SLM operation is guaranteed when all the lasing channels present similar output powers. It is also experimentally demonstrated that when a SLM behavior is achieved, lower output power fluctuations are obtained.}, organization = {Financial support from the Spanish Comisión Interministerial de Ciencia y Tecnología within projects TEC2007-67987-C02-02 and TEC2010-20224-C02-01 is acknowledged.}, publisher = {SPIE Society of Photo-Optical Instrumentation Engineers}, publisher = {Proceedings of SPIE, 2011, vol. 7753, 77533C}, publisher = {21st International Conference on Optical Fiber Sensors, Ottawa, 2011}, title = {L-band multiwavelength erbium-doped fiber ring laser for sensing applications}, author = {Pérez Herrera, Rosa Ana and Ullán Nieto, Ángel and Leandro, D. and Fernández Vallejo, Montserrat and Quintela Incera, María Ángeles and Loayssa Lara, Alayn and López Higuera, José Miguel and López Amo, Manuel}, }
